Looking at a refractomer, 0-10% for checking trees. It doesn't have ATC, but from what I've seen ATC is good for 10-30 degrees C, which is 50F on the low end. If I'm out early spring, I'll be well below that, so wondering if the one I looked at would be any different in the need to compensate?
Thanks,
